Dear Ganesh
I am unable to understand the purpose of your query. You could have given more information on the background and reasons on what type of information you are looking for.
However, in your next post you have asked whether NMR experience can be included in a Resume. I think this is your real query.
Yes, any experience which is related with a job; can be and should be included in one's resume.
Experience never goes waste and is always useful in letting others know about one's capabilities and potential.
By all means include it in your resume. What is important is not the status or type of the employment contract that you had with a company; but the nature of your job and your accomplishments.
Warm regards.
